Yak 27K-8 by king derelict - AModel - 1/72 - PLASTIC

[king derelict]

This is the third of my planned Eastern European kits and may be the most challenging. It was an impulse buy because I liked that 50s "supersonic" look. As I understand it the Yak 27K never made it beyond prototype although a reconnaissance did get in. to production.

This was also planned to see if I could improve my metal finish skills without too much heartbreak. Having had a quick look in the box I think it may also define the cliff edge of my sanity.

References are scarce and it seems that few models have made a public appearance.

Lots of parts in the box, quite a bit of flash, some distorted looking parts, sink holes and no locating pins. No major warping at first sight tough.

Instructions are somewhat vague and tend to indicate an approximate location of where to add parts

 

Fuselage halves have been cleaned up and the cockpit bucket assembled. Primer added while I try to determine colours. As far as I can tell Yaks had dark grey cockpits in the 50s not the turquoise seen in most Soviet aircraft.

I don't think much will be seen inside once the fuselage is closed up. 

The current overall plan is to complete the fuselage, add wings and tail surfaces then paint. The engine pods will be assembled and painted separately and then fitted. Obviously a lot of dry fitting before picking up the airbrush.

I see a lot of filler in my future.

Thanks for looking in.

Very cool subject Alan - looking forward to following along!

Alan, I think this pretty quickly morphed into the YAK-28 Firebar. Two operational versions, YAK-28P and YAK-28PM. The P carried 2 Anab missiles, the PM carried the Anabs and 2 Atoll short range IR missiles. I see at least the 2 Anabs in your parts jumble. This was considered a significant all weather interceptor threat. in the early 70s by NATO.

Good luck with the parts fit. My Firebar sits in the Box of Doomed projects. The nacelle fits are oath-inducing.

Thanks OC. There seems to be a lot of time waiting for paint to dry and idle hands get into mischief 😃

Thanks Mike. I suspect there are some interesting issues ahead

Hi Ken

You are right about the Yak-28 developing from the -27. All four missiles are included in the kit. I’m not sure if it makes sense to use any or all of them.

I had a brief look at the engine nacelles and I need to save up my allowance of bad language for them.

Welcome Dave

I started putting things together and have already got a flavour of how things may go. I started with the cockpit tub and the first problem was trying to fit seats and instrument panels. As shown there just isn't room. I sanded the bottom of the rear panel to set it at a different angle which gave be just enough space to the front seat. I dumped the joysticks, they were a mess of flash and were far too tall unless Yaks of the 50s used eye level sticks. I made a pair from 0.5 mm brass rod.

The instrument panels have dials sunk into them. I used very dilute white paint in each dial which had the effect of highlighting the rims and giving a bit of depth. A dab of Gators Grip acted as the glass. It will never be seen once closed up but it came out quite well.

The rear bulkhead is requiring some heavy-duty sanding to allow the two fuselage halves to come together. A bit more work still needed and I may need to adjust the front IP too.

I also made up the rear main landing gear bay and had to get pretty savage with teh sanding sticks there but it does not fit and the uselage will close back there

I closed up the fuselage which required a lot of iterations filing the cockpit bucket and nose landing gear bay to fit. The nose landing gear bay was a pale shadow of its initial shape by the time I had got it to fit  I made up the wings from the upper and lower halves. Again the sanding sticks and files were an essential part of the process.

I then had a look at the engine nacelles. The kit provides a first stage compressor and a final turbine stage with spray ring for the afterburner. They don't fit. I had to do some significant work with the files and reduced the sides almost to teh spray ring before it would fit.

Those oval turbine wheels never really caught on!

I originally thought I would paint the nacelles separately from the wings but fit checks showed that a lot of filing and filling was going to be necessary so I thought I should get it together before the primer goes on and get the gaps sorted out. The compressor / turbine discs wont be seen unless someone is very determined.

Dry fit suggests the wings will actually go on okay.

 

My fancy forward instrument panel is lost forever now that teh cockpit is closed up

 

I'm moving a bit slowly with this one because I am letting the glued joints set overnight to withstand the violence with the sanding sticks that will follow.

Nice job Alan.  Looks like another kit that will test your skills!

[king derelict]

Thanks Mike. I’m now at the point where your notes on filling gaps is very helpful. Actually although the nacelle to wing joints are nasty they seem to have cleaned up without leaving too much of a gap. Tailplanes fit quite nicely and the wings look as if they will be much better than the Condor. So far I’m using Vallejo putty and letting it dry overnight before attempting to sand it back.

Hey Alan, just be careful about using the Vallejo Putty.  I've heard it tends to shrink over time.  For bigger gaps, I mostly use Tamiya 2-part epoxy putty or CA which don't shrink.  

 

For small cracks and stuff, I will use things like Tamiya putty and have used Vallejo Putty.  I just get too nervous that with my slow build times, by the time I get around to painting - which could be weeks or months after construction - I'm back at square one with needing to fill (would be even worse if I had already painted!).
